+/*
+ * This code comes from John the Ripper password cracker, with reentrant
+ * and crypt(3) interfaces added, but optimizations specific to password
+ * cracking removed.
+ *
+ * Written by Solar Designer <solar at openwall.com> in 1998-2002 and
+ * placed in the public domain.
+ *
+ * There's absolutely no warranty.
+ *
+ * It is my intent that you should be able to use this on your system,
+ * as a part of a software package, or anywhere else to improve security,
+ * ensure compatibility, or for any other purpose. I would appreciate
+ * it if you give credit where it is due and keep your modifications in
+ * the public domain as well, but I don't require that in order to let
+ * you place this code and any modifications you make under a license
+ * of your choice.
+ *
+ * This implementation is compatible with OpenBSD bcrypt.c (version 2a)
+ * by Niels Provos <provos at citi.umich.edu>, and uses some of his
+ * ideas. The password hashing algorithm was designed by David Mazieres
+ * <dm at lcs.mit.edu>.
+ *
+ * There's a paper on the algorithm that explains its design decisions:
+ *
+ *	http://www.usenix.org/events/usenix99/provos.html
+ *
+ * Some of the tricks in BF_ROUND might be inspired by Eric Young's
+ * Blowfish library (I can't be sure if I would think of something if I
+ * hadn't seen his code).
